521. Indirect  Search for Dark Matter signatures in the Cosmic Rays as seen from Space

Marco Ricci (INFN - LNF)

Dark Matter and Rare Processes

Invited talk in the parallel session

The Dark Matter (DM) problem, experimentally, is tackled in different ways that can fall into two main complementary areas: direct and indirect searches. Among the indirect searches for DM, the observation from space of possible indirect signatures in the Cosmic Rays and in the gamma-ray sector has triggered increasing interest in the last years, with space missions like PAMELA, AMS, FERMI,...

80. The dark matter: DAMA/LIBRA and its perspectives

Pierluigi Belli (INFN Roma Tor Vergata)

Dark Matter and Rare Processes

Invited talk in the parallel session

The recent results of DAMA/LIBRA–phase2 experiment deep underground at Gran Sasso are presented. The improved experimental configuration with respect to the phase1 allowed a lower software energy threshold. The DAMA/LIBRA–phase2 data confirm the evidence of a signal that meets all the requirements of the model independent Dark Matter annual modulation signature, at high C.L. The model...

280. Improving the sensitivity to light dark matter with the Migdal effect

Dark Matter and Rare Processes

Invited talk in the parallel session

The search for dark matter (DM) weakly interacting massive particles with noble elements has probed masses down and below a GeV/c^2. The ultimate limit is represented by the experimental threshold on the energy transfer to the nuclear recoil. Currently, the experimental sensitivity has reached a threshold equivalent to a few ionization electrons. In these conditions, the contribution of a...

254. The Dark Matter Directionality Approach

Vincenzo Caracciolo (University of Rome "Tor Vergata")

06/07/2021, 11:00

Dark Matter and Rare Processes

Talk in the parallel session

Dark Matter particle candidates able to induce nuclear recoils can be
also studied using the so-called directionality technique. This approach is
based on studying the correlation between the nuclear recoils direction and
the Earth motion in the galactic rest frame.
Several experimental techniques to explore the directionality approach
have been proposed. In this talk, a review of such...

527. Dark photon search

Prof. Annalisa D'Angelo (Universita' degli Studi di Roma Tor Vergata & INFN Roma Tor Vergata)

06/07/2021, 11:30

Dark Matter and Rare Processes

Invited talk in the parallel session

The Heavy Photon Search (HPS) experiment searches for an electro-produced dark photon using an electron beam provided by the CEBAF accelerator at the Thomas Jefferson National Accelerator Facility.
HPS looks for dark photons through two distinct methods, a resonance search in the e+e- invariant mass distribution above the large QED background (large dark photon-SM particles coupling region)...

573. Mirror Dark Matter: direct detection, ultra cold neutrons and gravitational waves

Andrea Addazi (Sichuan University)

07/07/2021, 09:30

Dark Matter and Rare Processes

Invited talk in the parallel session

We will discuss Mirror dark matter searches from
Direct detection underground experiments, ultra cold neutrons and gravitational waves physics.

208. DAMA/LIBRA annual modulation and Axion Quark Nugget Dark Matter Model

Prof. Ariel Zhitnitsky (University of British Columbia)

07/07/2021, 10:05

Dark Matter and Rare Processes

Talk in the parallel session

The DAMA/LIBRA experiment shows $9.5\sigma$ evidence for an annual modulation in the $(1-6)\mathrm{k}\mathrm{e}\mathrm{V}$ energy range, strongly suggesting that the observed modulation has the dark matter origin. However, the conventional interpretation in terms of WIMP-nucleon interaction is excluded by other experiments. We propose an alternative source of modulation based on the so-called axion...

450. Leptophillic Dark Matter at Linear Colliders

Bhupal Dev (Washington University in St. Louis)

07/07/2021, 10:40

Dark Matter and Rare Processes

Invited talk in the parallel session

Leptophilic dark matter (LDM) could naturally arise in many beyond the Standard Model scenarios and could address certain experimental anomalies. We will discuss some model-independent collider constraints on the LDM effective couplings with the Standard Model sector, considering its production at a future electron-positron linear collider (with polarized and unpolarized beam options) in the...

277. Quantum mechanics tests in the Gran Sasso undergroud laboratory: collapse models and spin-statistics

Catalina Oana Curceanu (INFN - LNF)

07/07/2021, 11:15

Dark Matter and Rare Processes

Talk in the parallel session

We are experimentally investigating possible departures from the standard quantum mechanics’ predictions at the Gran Sasso underground laboratory in Italy.
In particular, with radiation detectors we are searching signals predicted by the collapse models (spontaneous emission of radiation) which were proposed to solve the “measurement problem” in quantum physics and signals coming from a...
